Natural gas from fracking is worse for climate than coal, says new study | Grist

Natural gas from fracking is worse for climate than coal, says new study | Grist: "Natural gas obtained through 'fracking' -- the increasingly common process of splitting open underground deposits with high pressure chemicals -- now has an even bigger strike against it than its potential to contaminate regional water supplies. Fracking, it turns out, yields more global warming per unit of energy than coal -- at least 20 percent more, and possibly up to twice as much."
